Abstract
A device for spraying a liquid for use in dye penetration inspection into an inner cavity of a workpiece for making a turbine engine part, the device including a workpiece support, a manifold for spraying the inspection liquid into the inner cavity, a manifold for sucking up and discharging the sprayed inspection liquid, and a mechanism for tilting at least a portion of the support from a substantially horizontal position to an inclined position in which the workpiece is inclined so that the inspection liquid sprayed into the cavity flows under gravity to a zone from which it is sucked up.
Claims16
A device for spraying at least one liquid for use in dye penetration inspection into an inner cavity of a workpiece, the device comprising:
- a support which supports the workpiece;
- a liquid delivery manifold that is connected to a tank and to a spray nozzle which sprays the liquid, at least part of the liquid delivery manifold being for receiving inside the workpiece when the workpiece is in position mounted on the support to enable the liquid to be sprayed into the inner cavity of the workpiece;
- a recovery manifold for recovering the sprayed liquid, which recovery manifold is for receiving at least in part inside the workpiece when the workpiece is in position mounted on the support, and is connected to a suction tube which extends into the inner cavity of the workpiece and sucks up the liquid sprayed into the inner cavity of the workpiece, and to a pump which discharges the sucked-up liquid;
- and
- a tilting lever which tilts at least a portion of the support from a horizontal position to an inclined position in which the workpiece is to be inclined so that the sprayed liquid in the inner cavity of the workpiece flows under gravity to at least one zone from which the sprayed liquid is sucked up by the suction tube,
- wherein said liquid delivery manifold and said recovery manifold are secured to said at least a portion of the support.
